COOKING APPARATUS.

SPECIFICATION forming part of ,Letters Patent No. 687,634, dated November 26, 1901.

Original application filed March 28, 1901, Serial No. 52,68%. Divided and this application filed May 23, 1901. Serial No. 61,644. (No model.)

To all whom t may concern: l

Be it known that we, EDWIN G. KASTEN- HUBER, residing at Bloomfield, in the county of Essex and State of New Jersey, and FRED A. JONES, residing at Schenectady, in the county of Schenectady and State of New York, citizens of the United States, have invented new and useful Improvements in Cooking Apparatus, (which is a division of our application led March 23, 1901, Serial No. 52,68%) of which the following is a specification.

This invention relates to a device by which such material as cotton-seed and other substance can be cooked preparatory to other operations-as, for example, pressing or the like for extracting oil; andthe invention resides in the novel features of construction set forth in the following specification and claims and illustrated in the annexed drawings, in which- Figure 1 is a sectional side elevation of the machine. Fig. 2 is a section along .fr w, Fig. 1.

In the drawings is shown a stationary heatin g-cylinder A, inclosingaheating coil or pipe D. This cylinder is shown in the concentric shells or cylinders C and B, which are fastened together and rotate on idlers d by means of sprocket or teeth E and chain or link belt c. The cylinders are placed in housing H, and the heater or steam-coil D being continued out of the inner heating-cylinder into the housing the latter will be suitably warmed or heated. The housing H is provided with openings H in its top, through which the driving chain or belt c may pass. The meal or material being fed through hopper F and entering shell C is fed along therein by blades or spirals to the exits 1. A series of holes-say four in number--with a corresponding number of blades, has been found efficient, and the material leaving this shell C through exit 1 enters the outer shell B, having a similar feeder or blade arrangement to feed the material to exit or holes 2.

To prevent the material'gathering at the end or head M of cylinder O, a guide-flange or frustum -shaped end piece K is inserted, so that the material will not clog at this end of the cylinder, but leave through exit l. The shells B C are also shown held separate and strengthened by ring L, and being connected these shells B C rotate together.

From exit 2 the material can be led off by a hopper or trough G to a compress mechan- -ism or elsewhere, as required by its subsequent use or treatment.

The machine can be so regulated that the raw meal can be passed through the cylinder at any speed and cooked to suit the condition of the same.

What we claim as new, and desire to secure by Letters Patent, is-n 1. A cooking apparatus comprising an inner stationary heating-cylinder, outer cylinders provided With blades and exits and made to rotate about the inner cylinder, ahousing made to surround the cylinders and a heating coil or conduit extended through the inner cylinder and into the housing substantially as described. l

2. A cooking apparatus vcomprising an inner stationary heating-cylinder, outer rotary cylinders provided with blades and exits, a housing made to surround the cylinders, and a coil or heat-supply in the heating-cylinder and housing substantially as described.

3. A cooking apparatus comprising rotary cylinders, a stationary heating-cylinder within the rotary cylinders, and a housing made to surround and heat the exterior of the cylinders substantially as described.

4. Avheating-cylinder, concentric shells or cylinders made to rotate together about the heating-cylinder, a housing made to surround the cylinders, and a coil or heat-supply for the cylinders and housing, said cylinders being provided with exits to communicate with one another and with blades or spirals for feeding the cylinder contents to such exits substantially as described.

In testimony whereof We have hereunto set our hands in the presence of two subscribing witnesses.

EDWIN G. KASTENHUBER. FRED A. JONES.
